When Pr 2.20 is set to 0 the deceleration ramp rate selected depends on the state of bit Pr 2.35 to Pr 2.37. These bits are for control by digital inputs
such that ramp rates can be selected by external control. The ramp rate selected depends on the binary code generated by these bits as follows:
When Pr 2.20 is set to 9 the appropriate deceleration rate is automatically selected depending on the value of Pr 1.50, and so a deceleration rate can
be programmed to operate with each reference. Since the new ramp rate is selected with the new reference, the deceleration applies towards the
selected preset if the motor needs to decelerate to reach the preset.
The jog deceleration rate is only used when the drive is changing speed because the jog reference has changed or to stop from the jog reference. It
is not used to go from the jog to the run state. This prevents the fast ramps normally used with jog from being used when changing between running
and jogging.
